Excellent. I'm happy to support one of my favorite services. Instapaper is one of the few apps (on iPad for me) that have actually improved the quality of my daily life -- how often can you say that about an app?

Specifically, it's retraining my brain to slow down, go deeper, and think critically.

My only concern would be rewarding the content producer, because I often skip the web page all together.

Perhaps integrating Flattr's API for those domains that have it set up?
